Answer:
It is the second one
Step-by-step explanation:
A proportional relationship happens when you get the same answer every time that you divide the y by the x.
(2,10) (4,20) (6,30)
10/2 = 5
20/4 = 5
30/6 = 5
That is not true for the other tables.
This answers would be 12x
The first one is B and the second is D
It's undefined, but I think you spelled it wrong.
Answer:
x=-7
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
40 + x+57 + 90 =180
Combine like terms
187 +x = 180
Subtract 187 from each side
187-187 +x = 180-187
x = -7
